BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to the field of devices and methods used in organizing long, slender, flexible materials (e.g., an electrical cable). More particularly, this invention relates to a device and method for coiling such a flexible material and maintaining it in its coiled form.

2. Description of the Related Art

It is generally accepted that long, slender, flexible materials, including electrical cables, are difficult to organize or maintain in an organized state, especially during transport or storage. Many seek to organize such materials by coiling them and, preferably, securing them such that they remain more or less in their coiled form. This can be very tedious, however, even leading some to disregard the virtue of organization altogether. Commonly, such persons can be seen transporting multiple electrical cables (or other long, slender, flexible materials) in a single tangled, knotted mass. Such practices can increase frustration and decrease efficiency. They can also reduce the lifespan of the electrical cables (or other long, slender, flexible materials). Accordingly, there is a need in the art for a coiling device that is simple and can be used quickly.

BRIEF SUMMARY OF THE INVENTION

One of the various embodiments of present invention includes (1) a cylinder that defines a cylindrical exterior surface having at least one groove that is straight and runs parallel to the axis of the cylinder and (2) a reel, around which a flexible material can be coiled. Each groove is provided for receiving at least part of an open tie (e.g., an open cable tie). The reel defines an axial through-opening for removably receiving the cylinder therethrough, such that the axis of the cylinder and the axis of the reel coincide. The cylinder is inserted in the reel via the axial through-opening, such that each groove is partially covered by the reel, resulting in a channel that later assists in preventing the open tie(s) from coming out of the groove(s) prematurely, i.e., before open ties are closed around the reel and the coiled flexible material. The flexible material is coiled around the reel and, thereafter, an open tie is introduced into each groove. Each open tie, which now occupies at least some of the space between the cylindrical exterior surface and the reel, is then closed around the reel and the coiled flexible material. The reel and the closed tie(s) cooperate to stabilize the coiled flexible material in its coiled state, even following the removal of the cylinder.

Device and Method for Coiling a Flexible Material

FIG. 1 shows an embodiment 10 of the device of the present invention, i.e., a device for coiling a flexible material. Therein, a flexible material 20, which in this example is an electrical cable, is shown coiled around embodiment 10, which includes a cylinder 30 that defines a cylindrical exterior surface 40. The cylindrical exterior surface 40 defines grooves 50, each of which is for receiving at least part of a tie 60, when such tie 60 is “open,” as shown in FIG. 1. Each groove 50 assists in stabilizing an (open) tie 60 in proper position relative to the coiled part 70 of the flexible material 20, at least until the (open) tie 60 is “closed” to stabilize the coiled part 70 in its coiled form, even after its removal from the cylinder 30. As shown in embodiment 10, the grooves 50 can be straight to facilitate the introduction of the ties 60. Also, as shown in embodiment 10, the grooves 50 can run parallel to the axis of the cylinder 30. This aids in ensuring that, when drawing, fastening, or uniting a tie 60 to close it around the coiled part 70 of the flexible material 20, the tie 60 runs parallel to the axis of the coiled part 70. Additionally, although the ties 60 shown in FIG. 1 are cable ties, one skilled in the art will recognize that other types of ties can be used in practicing the invention. Similarly, although the cylinder 30 shown in FIG. 1 is a right circular cylinder, one skilled in the art will recognize that other types of cylinders (e.g., an elliptic cylinder) can be used in practicing the invention.

The depth, width, and length of the grooves 50 is at least partly determined by the type of tie contemplated for use in practicing the invention, which can vary depending on the specific application. For example, some applications may require a cable tie that is extra heavy duty (e.g., 250 lb. minimum loop tensile strength). Such cable ties generally are wider (e.g., 0.5 inches) than the average cable tie. Accordingly, an embodiment of the invention that is intended to be compatible with such extra heavy duty cable ties should have grooves 50 wide enough to receive them. Similarly, some applications may require that the device of the present invention be especially suitable for coiling relatively long cables (or other flexible material). Accordingly, the length of the grooves 50 may need to be increased to receive longer ties capable of encircling a long, coiled cable. In some instances, the length of the cylinder 30 may need to be increased to accommodate either a long cable or such longer grooves.

FIG. 2 shows the stabilized coil of flexible material 90 that results from practicing the invention using embodiment 10 (see FIG. 1). As shown in FIG. 2, the stabilized coil of flexible material 90 includes the flexible material 20 (which, in this example, is an electrical cable) and the ties 60. The cylinder (see FIG. 1 at 30) no longer is present, and all of the ties 60 are closed around the coiled part 70 of the flexible material 20. The ties 60 stabilize the coiled part 70 in its coiled form.

FIG. 3 shows another embodiment 120 of the device for coiling a flexible material. The flexible material 20′ in this example is an electrical cable. In contrast to embodiment 10 (see FIG. 1), however, the flexible material 20′ is shown coiled around a reel 130. As shown in FIG. 3, the reel 130 defines an axial opening that is at least partially occupied by the cylinder 30′, which has been received therethrough such that the axis 64′ of the cylinder 30′ coincides with the axis 134 of the reel 130. In this configuration, the reel 130, which is removable, partly covers the grooves 50′ defined by the cylinder 30′, thereby creating a channel that can facilitate the introduction of the ties 60′ into the grooves 50′, if the user elects to place the reel 130 over the cylinder 30′ before introducing the ties 60′. Even if the user elects instead to introduce the ties 60′ into the grooves 50′ before placing the reel 130 over the cylinder 30′, the reel 130 can assist in preventing the ties 60′ from coming out of the grooves 50′ prematurely, i.e., before ties 60′ are closed around the reel 130 and the coiled part 70′ of the flexible material 20′.

FIG. 4 shows a stabilized coil of flexible material 160 that results from practicing the invention using embodiment 120 (see FIG. 3). The cylinder (see FIG. 3 at 30′) no longer is present, and all of the ties 60′ are closed around the reel 130 as well as the coiled part 70′ of the flexible material 20′. As shown in FIG. 4, the reel 130 provides support for the coiled part 70′. Accordingly, the reel 130 and the ties 60′ cooperate to stabilize the coiled part 70′ in its coiled form, even after the removal of the cylinder 30′ (see FIG. 3).

FIG. 5 shows a variant 130′ of the reel shown at 130 in FIGS. 3-4. The variant 130′ defines ridges 182 at each end, which can aid further in maintaining the form of the coiled part 70′ of the flexible material 20′ shown previously in FIGS. 3-4. The ridges 182 act as barriers that discourage the coiled part 70′ from slipping off the reel 130′ and can complement the ties 60′ (see FIGS. 34), especially in instances where one or more of the ties 60′, for whatever reason, are not closed tightly enough around the reel 130′ and the coiled part 70′ to prevent such slippage.

FIG. 6 consists of a flowchart showing an embodiment 180 of the method for preparing a stabilized coil of flexible material. As indicated at steps 182 and 184, respectively, a flexible material (e.g., an electrical cable) and an open tie (e.g., a cable tie) are provided. Additionally, as indicated at step 186, an object is provided that defines a substantially cylindrical exterior surface on which the flexible material can be coiled. It is required that the substantially cylindrical exterior surface define a groove for receiving at least part of the open tie. Optionally, the groove (1) is straight, or (2) is at least substantially parallel to the axis of the substantially cylindrical exterior surface, or (3) both (1) and (2). Next, as indicated at steps 188 and 190, respectively, the flexible material is coiled around the substantially cylindrical exterior surface, and at least part of the open tie is introduced into the groove defined by the substantially cylindrical exterior surface. If desired, step 190 can be performed before step 188. As indicated at steps 192 and 194, respectively, the open tie is looped around the coil of flexible material, and the open tie is closed to yield the stabilized coil of flexible material. Optionally, as indicated at step 196, the stabilized coil of flexible material is removed from the object.

FIG. 7 consists of a flowchart showing an embodiment 220 of the method for preparing a stabilized reel of coiled flexible material. As indicated at steps 222 and 224, respectively, a flexible material (e.g., an electrical cable) and an open tie (e.g., a cable tie) are provided. Additionally, as indicated at step 226, a cylinder is provided that defines a substantially cylindrical exterior surface that defines a groove for receiving at least part of the open tie. Optionally, as in embodiment 180, the groove (1) is straight, or (2) is at least substantially parallel to the axis of the substantially cylindrical exterior surface, or (3) is both (1) and (2). As indicated at step 228, a reel is provided, around which the flexible material can be coiled. The reel defines an axial through-opening for removably receiving the cylinder therethrough. Optionally, the reel has a ridge at each end (see FIG. 5). Next, as indicated at step 230, the cylinder is inserted in the reel via the axial through-opening, such that the groove is at least partially covered by the reel. In accordance with steps 232 and 234, respectively, the flexible material is coiled around the reel to yield a reel of coiled flexible material, and at least part of the open tie is introduced into the groove defined by the substantially cylindrical exterior surface. As indicated at steps 236 and 238, respectively, the open tie is looped around the reel of coiled flexible material, and the open tie is closed to yield the stabilized reel of coiled flexible material. Optionally, as indicated at step 240, the stabilized reel of coiled flexible material is removed from the cylinder.
